Adding And Removing in a text file

[rlagksquf]

Hi

I'm trying to make a VI that generates a textfile which saves some data each second and give it some timeframe so that it can maintain only the data that has been generated last 10 seconds or so

First I have made 2 different files, one is for saving some data each second into a text file, and the other one is for removing the data

but when i combined those two it doesn't seem to work.

Could anyone have a look at the file and comment on that?

thanks

A couple comments on what you are trying to do. First, doing this with a text file is going to be inherently difficult as you are going to be doing a lot of rewriting of the file. Second, having two VIs (1 to write the data and 1 to remove the old data) is a bad approach - why not design the algorithm so the file is only written to one time for each update cycle? Stop trying to make a poor design work and spend a little time thinking outside the box.

Hint: think about how you calculate a running average in LV, and what if the indicator out wasn't just an indicator but a file write?
